Problems solved by technology

Although copper alloy has good heat dissipation, it can meet the requirements of high machine speed and has high hardness, but because copper alloy belongs to the category of non-ferrous metals, it is difficult to smelt
In particular, the working conditions of glass molds during service are relatively cruel. Specifically, due to their frequent and rapid switching in the temperature range of 500-1100 ° C, the selection of materials for copper alloy glass molds and the preparation process If the process conditions cannot be strictly controlled, it will affect its service life

Abstract

A rare earth-copper alloy lightweight glass mold and a preparation method therefor, relating to the field of glass mold materials. The method comprises: putting weighed nickel, silicon, chromium, 50% of copper, and rare earth into a smelting furnace; after melting, stopping the heating of the furnace and adding the remaining copper; after melting, adding a deslagging agent to cover the melt; performing heating and removing the slags; at the same time, adjusting the melt by means of spectral analysis to contain 4.0-9.5% of nickel, 0.5-3.5% of silicon, 0.5-3.5% of chromium, 0.01-0.5% of rare earth, with the balance being copper; pouring the obtained rare earth-copper alloy lightweight glass mold melt into a molding sand wall in which a cold iron core is provided, and removing the cold iron core after the pouring is completed; introducing the obtained rare earth-copper alloy lightweight glass mold into a solution treatment furnace to perform solution treatment; and then, putting into the furnace to perform aging treatment to obtain a finished product. The mold has high thermal conductivity, high tensile strength, high hardness, excellent oxidation resistance and corrosion resistance.

Description

technical field [0001] The invention belongs to the technical field of glass mold materials, and in particular relates to a rare earth copper alloy lightweight glass mold, and also relates to a preparation method thereof. Background technique [0002] The lightweight glass mold mentioned above essentially refers to the glass mold used to process lightweight glass products (ie containers). With the continuous maturity and development of lightweight glass products technology, the speed of bottle making machines is getting higher and higher, so the requirements for thermal fatigue resistance and wear resistance of glass molds are becoming increasingly stringent. Manufacturers of high-end glass products tend to choose copper alloys as glass mold materials when manufacturing high-end lightweight glass products. Although copper alloy has good heat dissipation, it can meet the requirements of high machine speed and has high hardness, but because copper alloy belongs to the categor...
